Patent attributes
A head restraint device for improving quality of sleep inside passenger carriers includes a seat attachment assembly and a head restraint assembly including two elastic straps that are attached to the seat strap of the attachment assembly. The restraint assembly includes two adjusters coupled to the two elastic straps respectively, two head straps adjustably attached to the two adjusters, a face strap permanently attached to one head strap and attached to the other head strap via a loop and hook fastener. The two adjusters allow the face strap placed at center and the device to fit heads of different sizes. The face strap of bigger width provides better eye coverage and comfort. The restraint assembly restrains the movement of a head while the elastic straps absorb head motion and keep the passenger sleeping. The attachment assembly includes an adjuster for tightly attaching the device to a seat back or headrest.
